Surely you have heard about the benefits of Emery in the household, even if you are not a lover of crafts tinkering with his own hands.After all, each housing there knives, scissors and other piercing and cutting tools, from time to time require sharpening.But the price of Emery in most retail outlets will not please you!And so why not think about the independent production of this incredibly useful tool?

Many people use drills toget a hole in the metal with the help of a drilling machine or a drill.After a while the drill begins to warm and worse drilling, because it blunted.And all this happens pretty quickly if a drill to drill at higher speeds.There are cases when the drill breaks off in the middle, if it is "Zakusilo" at the outlet of the metal part and thus was not locked.
Accordingly, a blunt instru
to sharpen drill bits, you should use the purchased tool grinding machines, and you can hone using emery made with their own hands.Sharpener is a necessary and indispensable thing in the economy.With its sharpen virtually any tool, and it can be used for sanding wood.
in each store sold power tools sandpaper.Quite a large variety of them.Can be purchased as a very small nazhdachok to Blunt cutting tools to correct and quite powerful grinder, with which you can whittle down a thick layer of metal with any details.
best acquisition will elektronazhdak sided, one side of which is finishing, and other rough grinding wheels.These circles to prevent injuries should have guards - in case of destruction or damage to the range of pre engine running.It is also desirable to have at Electrosharpener adjustable stops working for sharpened Non-sparking tools and dashboards with safety glass.
are quite handy electric emery, which is governed by the speed of rotation.When removing the need to use large layer of increased speed, and the very "fine-tuning" of the cutting edge to do better on a low speed.This will exclude, of course, scorching metal.From time to time you need a tool for sharpening his cool in the bath with water.
Emery with his hands
in the hands of every man can be the engine of household appliances, and in the mind immediately begins to huddle question how to make sandpaper with their hands out of scrap materials.For this purpose, various electric motors, mounted on a shaft which is specially machined on a lathe attachment that are designed for clamping sanding disc.
For this purpose usually use engines from old washing machines production, such as the "Volga", "Riga", "Siberia", "Vyatka", etc.On these engines powerful enough typewriters and Reverse.Also from these washing machines use switches with the actuator.
Despite the fact that it seems it's pretty simple, the engine of the Soviet washing machine homemade sandpaper is not easy to put together.For example, one of the main issues is how the motor shaft to spread the grindstone.There's not always a thread, and hole diameter stone shaft diameter may be different.
therefore need special chiselled detail, which would compensate for this disparity.To make your own hands homemade sandpaper, you need to know his future options.In most cases, for the manufacture of a home using an emery typically asynchronous motors.
Emery is considered marginal for some revving 3000rpm.Whetstone at very high speeds can simply break.It is best to use at home with the engine 1000 - 1500 rpm.If the motor is used at 3000 revolutions per minute, should be present quite robust stone and made quality flange.The most commonly used high engine rpm is not grinding and polishing products.
To sandpaper to make their own hands, not necessarily should be used for such purposes, the powerful electric motors.Although speak skilled craftsmen that homemade grinding machine acceptable capacity is 400 W, and for home use enough engine capacity of around 100 - 200 watts from the Soviet washing machine.Of course, he is resourceful enough, but it's very good.
can be used for the manufacture of their own hands Emery three-phase and single-phase motors.In the single-phase network includes those and others.The device connects to the network via a single-phase capacitor.
to connect the motor and the need to carve stone flange.For such purposes, it is best to refer to the drawing turner emery stone the size of the inner diameter and the diameter of the motor shaft.And the rest - it's a matter of technology and the availability of scrap materials.
'll have to grind himself flange which is pushed onto the shaft and fixed by a bolt and a nut and washer from the left-hand thread.It is also necessary to take into account that on the nut and threaded flange, depending on the direction of rotation of our motor shaft.If clockwise rotation occurs - then it must be the left-hand thread, when suddenly the opposite - the thread has to be right-handed.While working desktop Emery Emery nut so spontaneously will twist.If we ignore this factor, the nut will work on unwinding, so the stone could fly.And of course this is extremely dangerous.
What's all the same do if point plugs for the manufacture of a certain diameter is not possible?In such a case can be useful pieces of pipe of suitable diameter and the gap between the sleeve and the shaft of the engine will compensate reeling tape between tissue-type plugs.In addition, the sleeve can be worn on one another.
In this case, the most important thing at the reel of tape - to observe uniformity in rotation to avoid the formation of big beat.The sleeve is made of a pipe diameter of 32 millimeters, equal to the inner diameter of emery circle.On it is put directly emery wheel, I could sit down with interference without reeling.
Such a system is quite dense bushes seated on the shaft.But with the help of bolts and washers fixing is required.At home, in the shaft, you can cut the thread using the tap while holding the grip of the motor shaft.It is necessary in this case to determine the correct diameter of the threaded hole.
Before making sandpaper in the home, you need to figure out the direction of his work.The emery, made with their own hands, you can change the direction of rotation of the rotor.If, for example, the motor from a washing machine, it is asynchronous, that is, when you change the corresponding coils can change the direction of rotation.Also in the engine from the old home appliances production is 3 - 4 output.For example, at 4 findings change the direction of rotation does not take much.
For this purpose we find starting and running winding by using the tester.The resistance level of the working coil usually is 12 ohms, and is close to the starting 30 ohms.Working winding is connected to a network of 220 W, and the pad is securely connected at one end to one terminal of the coil, and the second end to touch briefly to the second terminal coil and then immediately drop it (this is usually used for special relay).If you use a capacitor motor, the circuit switching will be different.
So, your sandpaper is spinning in one direction, and if, for example, to change the conclusions of the starting winding in places, respectively, then the motor will rotate in the opposite direction.It is possible in principle generally do not trigger coils, in this case after the operating winding network need abrasive stone krutnut a certain direction, and thereafter the machine will work.
After making homemade sandpaper should figure out how to install it correctly on the bench.This is done by means of a bracket, which is also removed from the washing machine and fastened to the bench with bolts.The engine on the other hand rests on the angle that supports it in a horizontal position, and has a cutout that completely follows the shape of the motor housing.To reduce vibration, is put on the border area, made from a piece of rubber hose.
To avoid injury from flying debris and saw abrasive disc while working on a grinding machine, made with your own hands, you need to cover.Produce the best of its thicker metal - 2 - 2.5 millimeters.It can be folded in half-ring metal strip.
Under the working body of emery directly need to tie a small piece of galvanized iron sheet that protects the bench from sparks during operation.All work for their own safety should be carried out specifically for this use glasses or other protection.
as devices for Emery can be used Plexiglas, a thickness of 5 millimeters.Such glass is attached to the motor housing by means of test portions, it can be folded by 180 degrees.Also for the usefulness of the machine it is necessary to stop the workpiece to make podruchnik.
Of course, you can not use an electric sharpener doubt!It is not going to be used each time a new ax or a drill.And buy this emery somehow expensive.But out there, you only spend a little time and collect sandpaper hands.Follow our instructions carefully, provide the necessary protection of the machine and do not neglect safety requirements during operation.
